Abstract
The present invention relates to a mobile communication technology, and discloses a reporting method of scheduling information in High Speed Uplink Packet Access (HSUPA) which improves radio resource utilization rate when the scheduling information are reported to the SI. In this invention, when a user facility fails an unnecessary SI report, it does not trigger a new SI report. The unnecessary SI report means only the SI report triggered due to the D in MAC-e PDU being greater or equal to 18.
Description
Technical field
The present invention relates to mobile communication technology, particularly high-speed uplink packet access technique.
Background technology
Third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") vital tissue as moving communicating field has promoted 3G (Third Generation) Moblie (The Third Generation, be called for short " 3G ") standardization effort of technology, the carrying of uplink and downlink business all is based on dedicated channel in its early stage protocol version.
Along with the development of mobile communication technology, 3G technology is also in constantly development evolution.High speed downlink packet inserts (High Speed Downlink Packet Access is called for short " HSDPA ") and high speed uplink packet access (High Speed Uplink Packet Access is called for short " HSUPA ") is exactly the important evolution of 3G technology.The scheduling of the packet among HSDPA and the HSUPA and re-transmission etc. are controlled by base-station node (Node B).
Wherein, HSDPA was introduced in 3GPP the 5th edition as down high-speed data bag access technology, and (Release 5 in 2002, abbreviation " R5 ") in the version, and 3GPP the 6th edition (Release 6, abbreviation " R6 ") carried out in partly improving, it adopts 2 milliseconds of shorter (ms) Transmission Time Intervals (Transmission Timing Interval is called for short " TTI "), to realize quick self-adapted control.Use adaptive coding and modulation (Adaptive Modulation and Coding is called for short " AMC ") and mix automatic repeat requests (Hybrid Auto Repeat reQuest is called for short " HARQ ") in physical layer.
HSUPA is called the dedicated channel (Enhanced Dedicated Channel, be called for short " E-DCH ") of enhancing again, as the high speed uplink data packet access technique, also has been incorporated among the 3GPPR6 in 2004.Similar with HSDPA, HSUPA has also adopted 2ms TTI and shorter frame length to realize quick self-adapted control, use HARQ and based on the fast uplink dispatching technique of Node B, improved up spectrum efficiency, also have remarkable advantages such as uplink speed is fast, propagation delay time is little, thereby provide more effective support for the application of grouping data services such as real-time game business, file are uploaded, broadband multimedia services.
In addition, extensively adopted for the third generation air interface technologies of the 3G of representative with universal mobile telecommunications system (Universal Mobile TelecommunicationSystem is called for short " UMTS ").The effect of Radio interface protocols is to set up, reconfigure and the releasing wireless loading business, for example, the universal mobile telecommunications system terrestrial wireless inserts (UMTS Terrestrial Radio Access, abbreviation " UTRA ") Frequency Division Duplexing (FDD) (Frequency Division Duplex, be called for short " FDD ")/time division duplex (TimeDivision Duplex is called for short " TDD ") business.Agreement relevant with HSDPA in wireless air interface (Uu interface) is from control plane, mainly be divided into three layers: physical layer (Physical) is ground floor, media access control protocol layer (Medium Access Control, be called for short " MAC ") and radio link control (Radio Link Control, abbreviation " RLC ") layer is the second layer, and corresponding radio resource control protocol (Radio Resource Control is called for short " RRC ") layer is the 3rd layer.
Physical layer provides service by transmission channel to the MAC layer, and wherein, the feature of transmission channel is by the type and the characteristics determined of its transmission data; The MAC layer provides service by logic channel to rlc layer, and the feature of logic channel also is to be determined by the data type that sends; Rrc layer uses the business of rlc layer to come command transmitting.
In the MAC layer, logic channel is mapped as transmission channel.The MAC layer also according to the moment source speed of logic channel, is the suitable transformat of each transmission channel selection (Transport Format is called for short " TF ").The selection of TF is controlled to be each TF combination of sets that is connected definition with admittance and is closely related.
Wherein, at subscriber equipment (User Equipment, be called for short " UE ") and universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network, abbreviation " UTRAN ") the MAC layer structure of the E-DCH of side distinguished as depicted in figs. 1 and 2, and the MAC layer of E-DCH also comprises MAC-e and two sublayers of MAC-es.The MAC-e entity of UTRAN side is in Node B, and the MAC-es entity is in service wireless network controller (Serving Radio Network Controller is called for short " SRNC "), and the MAC-e entity of UE side and MAC-es entity are in same functional unit.
MAC-e protocol Data Unit in the MAC-e entity (Protocol Data Unit, abbreviation " PDU ") structure as shown in Figure 3, the payload part of MAC-e PDU comprise a plurality of multiplexing together MAC-es PDU, optionally be used for schedule information (the Scheduling Information of 18 bits of up fast packet scheduling, be called for short " SI "), and be used to make the length of MAC-e PDU to equal the possible filling field of the E-DCH transport block length of appointment; The head of MAC-e PDU is then indicated (Data Description Indicator by the data description of corresponding 6 bits of each MAC-es PDU, abbreviation " DDI ") the N field of field and 6 bits constitutes, and optionally is used to identify the DDI0 field that MAC-e PDU head finishes.Wherein, the DDI field is used to refer to the size of the MAC-d PDU of MAC-es PDU cascade; The N field is used to refer to the number of the MAC-dPDU of a MAC-es PDU cascade.
According to 3GPP protocol specification TS25.321, whether the form basis of MAC-e PDU transmits the size of SI and remaining bits number (D), be that the E-DCH transport block length deducts remaining bit number after the length of the contained n of a MAC-e PDU MAC-es PDU and corresponding n DDI field and n N field, have following four kinds of structures:
(1) transmit separately under the situation of SI, whole M AC-e PDU promptly is made of the SI of this 18 bit long, and the structure of MAC-e PDU in this case as shown in Figure 4;
(2) as D during less than 18 bits, then do not transmit SI, remaining bits is a filling bit, and the structure of MAC-e PDU in this case as shown in Figure 5;
(3) when D more than or equal to 18 bits, and during less than 24 bits, then with SI directly level be associated in the end of MAC-es PDU, remaining bits is this SI and filling bit (0-5 bit), the structure of MAC-e PDU in this case as shown in Figure 6;
(4) as D during more than or equal to 24 bits, then the SI level is associated in the end of MAC-es PDU, and at the additional DDI0=" 111111 " of the end of MAC-e PDU head, remaining bits is this SI, DDI0 field and filling bit, and the structure of MAC-e PDU in this case as shown in Figure 7.
According to 3GPP protocol specification TS25.321, when UE is in the state that does not allow to send data, promptly authorization of service (Serving Grant is called for short " SG ") parameter is " Zero Grant "; Perhaps all be in non-active state when all HARQ processes, have new data to need to send in the up data buffer, and UE is in when allowing to send the state of data, in both cases, UE all can trigger the SI report.
Specifically, when UE is in when not allowing or allowing to send the state of data, the SI report mainly is based on certain cycle triggering, this triggering cycle is by information element (InformationElement in the RRC message, be called for short " IE ") " Periodicity for scheduling Info-grant (schedule information cycle-mandate) " and " Periodicity for scheduling Info-no grant (schedule information cycle-unauthorized) " defined, for example, be 2ms, 4ms, 10ms, 20ms, 50ms, 100ms, 200ms, 500ms or 1000ms equivalence.The SI triggering cycle is to be handled information such as resource situation to determine based on the scheduling strategy of E-DCH and Node B by system.In addition, according to this standard, the SI report can also be by other Event triggered.
In actual applications, there is following problem in such scheme: the wireless resource utility efficiency during SI reporting is lower.
Cause the main cause of this situation to be, because as the D of MAC-e PDU during more than or equal to required 18 bits of multiplexing SI, UE promptly triggers reporting that SI reports.SI report in this case is nonessential, just in order to make full use of idle Radio Resource, but when this SI report bust this, the SI that causes thus report transmission once more but becomes essentially, and this SI that triggers once more report may be transmitted and caused unnecessary radio resource consumption by following mode:
Transmit this SI report separately with MAC-e PDU, therefore need take certain ascending wireless resource transmits E-DPCCH/E-DPDCH;
Count D less than 18 bits if transmit the remaining bits of the MAC-e PDU on the TTI of this new SI information, then must select bigger E-DCH transmission block to fill, will cause the waste of ascending wireless resource like this with transmission SI report and with remaining bit.
Summary of the invention
In view of this, main purpose of the present invention is to provide method for submitting scheduling information in a kind of high speed uplink packet access, and the wireless resource utility efficiency when making SI reporting is improved.
For achieving the above object, the invention provides method for submitting scheduling information in a kind of high speed uplink packet access, comprise following steps:
If subscriber equipment only reports this schedule information owing to the current remaining bits number of waiting the MAC-e protocol Data Unit sent out reaches predetermined first threshold value, then when this reporting of scheduling information (SI) failure, stop reporting of the new schedule information that therefore triggers.
Wherein, also comprise following steps:
If described subscriber equipment only reports this schedule information owing to the current remaining bits number of waiting the MAC-e protocol Data Unit sent out surpasses described first threshold value, then mark carries the described MAC-e protocol Data Unit of this schedule information;
Described subscriber equipment judges when the described schedule information that reports failure belongs to the described MAC-e protocol Data Unit that is labeled, and stops reporting of the new schedule information that therefore triggers.
In this external described method, when the described MAC-e protocol Data Unit number of retransmissions that is labeled surpassed predetermined second threshold value, then described subscriber equipment was judged this reporting of scheduling information (SI) failure.
In this external described method, when described subscriber equipment received the affirmation information that the described MAC-e protocol Data Unit that is labeled is received from the dedicated channel Serving cell of non-enhancing, then this subscriber equipment was judged this reporting of scheduling information (SI) failure.
In this external described method, described remaining bits number deducts remaining bit number after the length of all contained MAC-es protocol Data Units of MAC-e protocol Data Unit and corresponding data description indication field and N field for the dedicated channel transport block length that strengthens;
Described first threshold value is 18 bits.
By finding that relatively the main distinction of technical scheme of the present invention and prior art is, when subscriber equipment reports failure at nonessential SI, does not trigger new SI and reports.The SI that nonessential SI reports finger only to trigger because of D 〉=18 of MAC-e PDU reports, and is not that the SI that is triggered by the incident of agreement regulation or cycle reports.Have technology prejudice in the prior art, think that all SI report failure should retransmit, and do not see that reporting of some SI itself is exactly nonessential, the present invention has overcome this technology prejudice.
Difference on this technical scheme has brought comparatively significantly beneficial effect, and the re-transmission when promptly by cancellation nonessential SI being reported failure can be avoided unnecessary radio resource consumption, helps improving systematic function.
Utilize the idle transmission bandwidth transmission of MAC-e PDU SI report in the prior art by keeping, make the E-DCH dispatch unit can obtain extra SI information, and therefore improve systematic function, with the prior art compatibility.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention by only since the current D that waits the MAC-e PDU that sends out more than or equal to 18 report the SI bust this time, therefore UE stops and the reporting of the new SI that triggers.Because the SI of Fa Songing is nonessential SI in this case, by reporting of the new SI report that stops when the nonessential SI bust this therefore triggering, can avoid unnecessary radio resource consumption, help improving systematic function.
The SI report method as shown in Figure 8 during the high speed uplink packet of better embodiment of the present invention inserted.
In step 801, UE judge SI report reason whether only because the current D of the MAC-ePDU that sends out that waits more than or equal to 18, if then this SI is nonessential, changes step 802 over to; Otherwise this SI triggers reasons such as cycle or incident and triggers owing to SI, necessary for network side, changes step 803 over to.
In step 802, UE only comprises because the MAC-e PDU of the SI that D reports more than or equal to 18 makes marks this, sends then, enters step 804.
In step 803, UE directly sends MAC-e PDU according to prior art, enters step 804 equally.
In step 804, UE judges whether the reporting of SI that belongs to the MAC-e PDU that is labeled fails, and also, when SI reported failure, UE judged whether to belong to the MAC-e PDU that is labeled, if then change step 805 over to; Otherwise, change step 806 over to.
Specifically, have two kinds to judge that SI reports the situation of failure:
First kind of situation, when the MAC-e PDU number of retransmissions that is labeled surpassed predetermined threshold, UE judged that this SI reports failure.
Second kind of situation, when UE received the affirmation information that the MAC-ePDU that is labeled is received from non-E-DCH Serving cell, UE judged that also this SI reports failure.The transmission of MAC-e PDU is successful in this case, can not carry out grand diversity reception but be that the E-DCH Serving cell is employed because of SI information in RNC, reports failure so also be judged to be SI.
In step 805, because in this case SI is that network side is nonessential, so UE stops this SI and reports failure and trigger new SI and report process ends.
In step 806, because SI in this case is that network side is necessary, so UE triggers new SI and reports process ends.
In above-mentioned better embodiment, only trigger and give the correct time on the SI because of D 〉=18 of MAC-e PDU, not to trigger because of the incident of agreement regulation or cycle to give the correct time on the SI in other words, think that nonessential SI reports.Yet along with the development of HSUPA technology or in concrete enforcement; the situation that other nonessential SI reports also may appear; this also can directly use the solution of the present invention that its re-transmission is forbidden; thereby reach the technique effect that reduces radio resource consumption, therefore also belong to protection scope of the present invention.
Those of ordinary skills understand easily, above-mentioned better embodiment has kept utilizes the idle transmission bandwidth transmission of MAC-e PDU SI report in the prior art, make the E-DCH dispatch unit can obtain extra SI information, and therefore improve systematic function, with the prior art compatibility.
Though pass through with reference to some of the preferred embodiment of the invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
